Why should we treatment about the new findings – launched this week – from NASA’s Parker Solar Probe? This new NASA video describes how the photo voltaic wind – a stream of billed particles from the sun – impacts earthly astronauts and technologies.
Scientists launched 4 new papers in the journal Mother nature this week, outlining new discoveries from NASA’s Parker Photo voltaic Probe, which has occur nearer to our mother or father star than any past spacecraft. This new NASA video – introduced November 24, 2019 – describes why we need to treatment. It describes the photo voltaic wind, the stream of particles that commences in the sun’s interior atmosphere and continues out outside of our photo voltaic method.
Below on Earth’s surface, we’re secured from the photo voltaic wind by our blanket of atmosphere. In truth, earthly skywatchers appear ahead to announcements of storms on the sun, which mail the solar wind outward. They can established off geomagnetic storms that guide to gorgeous displays of auroras, or northern lights, generally witnessed at substantial latitudes and somtimes, if the photo voltaic wind is solid more than enough, extending down into reduce latitudes.
But these exact solar storms can also disrupt orbiting satellites (they can be the cause we all have cell cell phone concerns on the very same day). They’ve been identified to bring about earthly power grids to are unsuccessful, producing blackouts. And they’re a hazard to our astronauts in room.
How sturdy is the solar wind? The wind speed of a Group 5 hurricane can top at perfectly more than 150 miles (240 km) for each hour. The normal pace of the photo voltaic wind is practically a million miles (1.four km) for every hour.

Bottom line: NASA video on the solar wind and how it has an effect on Earth.
